SPECIFICATION forming part of Letters Patent No. 670,522, dated March26, 1901. 7

Application filed March 9, 1900. Serial No. 7,978. (No model.)

parts secured together with such absolute 'inafter described, and

firmness or rigidity as to prevent all rattle or lost motion between theparts.

To these ends this invention consists of the golf-stick as an article ofmanufacture and of the combinations of parts therein, as heremoreparticularly pointed out in the claims at the end of this specificationIn the accompanying drawings, Figure 1 is a side View, partially brokenaway, of the main part of a golf-stick constructed according to thisinvention. Fig. 2 is a perspective view of the handle pieceor shank of agolfstick constructed according to this invention and of the partscarried thereby, and Fig. 3 is a perspective view of the adjustableblade of a golf-stick constructed according to this invention.

In playing golf it is customary for each player to use a considerablenumber of golfsticks. These gelf-sticksdiffer among themselvesprincipally in respect to the angles at.

which the faces or driving-surfaces are set with respect to thehandle-that is to say, a player desiring to make a stroke which willlift the ball high into the air will ordinarily employ a golf-stickhaving its driving-face set at a considerable angle to the handlethere-.

of, while in approaching a hole when it is not desired to lift the ballinto the air the player will use a golf'stick having its driving-facesubstantially in line with the handle. The

several golf-sticks employed necessarily vary among themselves in weightand stifiness.

To avoid the expense of purchasing a considerable number of differentgolf-sticks and to avoid the labor of carrying the same around thecourse, ithas heretofore been proposed to provide adjustable golf-stickswhich may be adjusted to set their striking-faces at diftion istherefore to provide a clamping or set:

ting mechanism for securing the adjustable blade or' head piece of anadjustable golf-stick to its handle with substantially the same degreeof rigidity as if these parts were formed integrally.

- 'Referring to the accompanying drawings and in detail, a golf-stickconstructed accordingto this invention, as therein illustrated,comprises a handle 10, which may be of the ordinary wooden type;

Fitting onto the end of the handle 10 is a handle-piece or shank 11. Asshown most clearly in Fig. 2, the handle or shank 11 is provided in itsface with recesses or depressions 12.

The adj ustable blade or footpiece 13 of the golf-stick hereinillustrated is provided on its face with a projection or lug 14 forengaging any one of the recesses 12. The recesses 12 are preferably openat their ends, so that when the parts are drawn together by the clampingmechanism, hereinafter described, the log 14 will force any mud or dirtout of the slot or recess 12 into which the same is fitted. The clampingmechanism which I employ 'for securing these parts together comprises ascrew extending loosely through the shank and which is threaded into theadjust able blade and is also threaded through a clamping-nut. The screwwhich I preferably employ has differential screw-threads-that is to say,the portion of the screw fitting into the adjustable blade is providedwith screwthreads of one pitch or coarseness, while the screw-threadsfitting into the clamping-nut have a difierent pitch or coarseness. The

clamping-nut is preferably provided with an' The forward part 16 of thescrew 15, whiehis threaded into the blade 13, has serew-th reads whichare coarser than the screw-threads 17 of the screw 15, which arethreaded into the clamping-nut 19. The clamping-nut 19 has anupwardly-extendiug arm 20, with a lug or projection at its upper end,which snaps into a recess in the handle'piece or shank 11.

By means of this construction I have provided a clamping device whichmay be set so that by turning the lever 20 to its upright position anydesired degree of pressure may be exerted between the shank-piece andblade of the golf-stick. For example, suppose that when the blade is setto the desired angle it is found that the parts are not clamped togethertightly enough to secure the desired rigidity. If this should be thecase, the clamping lever is first turned from its locked po sition andthe screw 15 is advanced orturned. \Vhen this has been done, thedifference in pitch between the threaded sections 16 and 17 of the screw15 will draw the parts together, so that when the clamping-lever 20 isagain turned to its clamped or locked position it will exert a greaterdegree of pressure, and by thus varying the adjustment any desireddegree of pressure may be secured and the parts may be clamped togetheras firmly or rigidly as desired, while at the same time the use of aclamping device of this construction will fully compensate for anylooseness arising from long-continued use.

I am aware that numerous changes may be made in the details ofconstruction of a golfstick without departing from the scope of myinvention as expressed in the claims. I do not wish, therefore, to belimited to the form of construction which I have herein shown anddescribed; but

What I do claim, and desire to secure by Letters Patent of the UnitedStates, is

1. As an article of manufacture, a golf-stick comprising a handle-pieceor shank, an adjustable blade, a clamping-nut, and a differential screwhaving screw-threads of one pitch threaded into the blade, andscrew-threads of a difierent pitch threaded into the clampingnut,whereby the pressure exerted between the parts by turning theclamping-nut to its clamped position may be varied as desired,substantially as described.

2. As an article of manufacture, a golf-stick comprising a handle-pieceor shank 11 ha"- ing sockets or recesses 12, an adjustable blade havinga lug or projection 14 for engaging, the recesses 12, a clampingnuthaving an operating handle or lever, and a screw 15 threaded both intothe adjustable blade and the clamping-nut, that portion of the screwwhich is threaded into the adjustable blade having coarser threads thanthat portion thereof which is threaded into the clam ping-nut,substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
